Set the following parameters:
(Refer to the previous section to get further infor-
mation on these parameters)
First stage
Both tunnel doors start opening when the
start temperature of this fan stage is
reached. Select what fan stage signals the
beginning of tunnel ventilation.
Probe set 2 starts at stage
Select at what fan stage the controller starts
measuring the room temperature with the
second probe set.
Closing vent doors
Select the fan stage at which vent doors
must close.
This menu is only available if vent doors are not
closed in natural ventilation (see Installation Setup
in section 4.5).
Minimum outdoor temperature
Select the outside below which both tunnel
doors remain closed (or select “Off” to dis-
able this function).
Available if an outside temperature probe is en-
abled (section 4.7.1).
Minimum age
Select the animal age below which both tun-
nel doors remain closed. Adjustable from 1
to 450 days (or select “Off” to disable this
function).
Available if age-based functions are enabled in the
Installation Setup (section 4.5).
TEMPERATURE-BASED TUNNEL DOORS:
Opening times
Assign a tunnel door opening time with the
start-up of each tunnel fan stage. If two tun-
nel doors are used, assign these opening
times separately for each tunnel door. Open-
ing times can be adjusted from 0 to 900 sec-
onds (15 minutes).
Available if tunnel doors operate according to the
temperature.
PRESSURE-BASED TUNNEL DOORS:
If two tunnel doors are used, set the following pa-
rameters separately for each of them:
Pre-opening delay
Set the time that is required to pre-open the
door before activating tunnel fans. Adjust-
able from 0 to 120 seconds.
Wind effect delay
Select what time delay the controller must
wait prior to moving tunnel doors when the
pressure level exceeds a pressure set point.

0-10V Ventilation Outputs
The controller has a 0-10V output which can ei-
ther be used to control an air inlet or variable-speed
fans. To operate this output, the controller refers
to the average temperature reading of probes that
are assigned to the 0-10V output (see sec. 4.7.3).
This section explains how a 0-10V ventilation out-
puts work.
The 0-10V ventilation output starts at its minimum
intensity when the average temperature of its
probes reaches the start temperature. The fans
increase in intensity as the temperature increases;
they reach their maximum intensity when the tem-
perature rises to the Maximum Temperature pa-
rameter setting.
0-10V Mode: Automatic / Manual
You can manually control the intensity of the
0-10V output by using the manual control mode.
While this mode is used, the controller stops con-
trolling the output and lets you choose the intensity
of the output.

** Accessible if a 0-10V ventilation output is enabled in the
Installation Setup (section 4.5).
•
Set the following parameters:
Mode:
Set the operating mode of the 0-10V
output: select “Automatic” if you want the
controller to control the output or select
“Manual” to specify the intensity of the out-
put yourself.
Current output:
This is the current intensity
of the output. This intensity can be modified
while the manual mode is enabled above.
Start temperature:
Set the start tempera-
ture to the desired value. This temperature
can be set as a fix value (absolute) or it can
be related to the set point: this means that
when the set point changes, the start tem-
perature is adjusted by the same amount.
(refer to section 4.5 to specify if the start
temperature of the 0-10V follows the set
point or not).
Minimum & max speeds:
Set the minimum
and maximum speeds of the 0-10V output.
The maximum speed must be greater than
the minimum speed.
Maximum output at:
Set the temperature
at which the output reaches its maximum
speed (this parameter must be set to a
greater value than the start temperature).
Stop at:
This is the temperature below which
the 0-10V output stops.
